Researchers from the Yale School of Public Medicine said evidence of the disease was discovered in 18 patients in New England and New York, including the patient from Nantucket.

The disease is so new that it doesn't have a name.

It's the first time an infection in humans from a bacterium known as Borrelia miyamotoi has been confirmed in the U.S.

Dr. Sam Telford, an expert on tick-borne diseases, authored the paper in the New England Journal of Medicine on the new illness.

He says the new disease now adds up to five different illnesses caused by deer ticks.

"We need to start talking about prevention. Nobody's doing anything about controlling ticks. We can start by cleaning up our yards and reducing the deer population by increasing hunting," he said.

The disease is transmitted by the deer tick, which also infects people with Lyme disease, babesiosis and anaplasmosis. Symptoms include fever, headache, muscle ache and fatigue and is treated with the same antibiotics used to treat Lyme.

A day after Trevor Noah was declared the new host of "The Daily Show," complete with the blessing of the exiting Jon Stewart, graphic tweets targeting women, Jews and victims of the Ebola virus are causing a social media backlash.
